Abstract:
PURPOSE:The aim of this study was to evaluate the cardiovascular outcome in patients with the undetermined form of Chagas' disease and whether or not it is related to the infectious disease in the long-term. METHODS:One hundred and sixty patients were prospectively followed-up at three month intervals for up to 177 months. RESULTS:Twenty and three (14.4%) patients developed hypertension complicated by ischemic stroke in two (1.2%) and symptomatic heart failure in one (0.6%). Cardiac arrhythmias occurred in four (2.4%) patients corresponding to isolated ventricular ectopic beats in two (1.2%), isolated supraventricular ectopic beats in one (0.6%) and an isolated episode of acute atrial fibrillation in another (0.6%). Two (1.2%) patients developed symptoms of coronary artery disease, one of them had one episode of acute chest pain diagnosed as myocardial infarction and the other had chronic chest pain diagnosed as angina. CONCLUSION:Hypertension is the most common cardiovascular disease occurring in the long-term follow-up of patients with the undetermined form of Chagas' disease. Cardiac rhythm disturbances and coronary artery disease were not more frequent than those generally found in a healthy population. These data confirm a favorable long-term prognosis in patients with the undetermined form of Chagas' disease.
